The _themes folder is not a default folder in SharePoint Designer 2010. For the _themes folder to show up under All Files in SharePoint Designer 2010, you add a custom theme to the Site Theme option under the Look and Feel label in your Website Site Settings.

I will continue to monitor this thread for further posts or questions.

Thanks for coming to the communities with your concerns about accessing the _themes folder through the style sheets option in SharePoint Designer 2010.

Unfortunately, I am unable to reproduce your issue. When I click on the Style Sheet option on any website page and click view default CSS, it brings me to the theme.css page in SharePoint Designer as long as I have SharePoint Designer open.

I will continue to monitor this thread if you have any additional questions.

Sorry but that wasn't what I asked. You have css files set to open in SPD. By default they open in notepad. If I change the program associated with css files to open in SPD, yes the default css file opens in SPD.

But my questions was: why is the _themes folder available in some accounts and not others?You can clearly see the difference in these 2 screenshots - 2 differnet P1 accounts logged in as admin:

I do not have the “_themes” or “365Themes” folders in top-level of the All Files folder in SharePoint Designer 2010 for my public-facing website however my themes folder is in the “_catalogs” folder in the All Files folder.

I will continue to monitor this thread for further posts or questions.

Our team supports connecting a website or site collection to SharePoint Designer 2010 however we do not support SharePoint Designer 2010. Unfortunately, I do not have the answer for you however it may show up if there is custom CSS on the website.

SPD doesn't determine the structure/permissions of a 365 account, so the question isn't about SPD. The custom css file is in the Resources folder for both accounts (when activated) but there are a whole bunch of other css and image files available under _themes/37 in one account but not the other. So the questions remains: why is that and how do I get consistency across accounts?
